What is the value of an 1865 US 2 dollar silver certificate?

The first federally-issued $2 silver certificates were dated 1886. However there were many privately-issued bills at that time.

Please check your bill again and post a new, separatequestion with more information that might help to ID it, such as the name of the issuing bank or a short description of the picture(s) on it. Words such as LIBERTY, UNITED STATES, etc. are not unique identifiers.
